"In instrumental drawing, as in all phases of his professional development, the engineer should strive to achieve a high degree of knowledge and skill, working on his own to fill the unavoidable gaps in his formal education. Standards of quality and accuracy should be as high as possible, commensurate with the nature of the assignment and the time allowed for its completion. Unskilled and indifferent work on the drawing board is unworthy of either the aspiring or practicing engineer.""One might as well inquire, is it worth the time required to put on a clean shirt, to have the suit pressed and the shoes shined, or to brush the hair?"Engineering Graphics, Robert H. Hammond, Carson P. Buck, William B. Rogers, Gerald W. Walsh, Jr., and Hugh P. Ackert, 2 nd Ed., Robert E. Krieger Publishing Company, Huntington, NY, 1979
lignumCAD is a tool for designing furniture. Its primary features will be:
A notebook metaphor where each page is a view of an aspect of the design.
A sketching mode which allows rapid development of different views of a piece.
2D and 3D representations can be created from a single solid geometry model.
Parametric relations between dimensions allow changes to be propagated from either the 3D solid model, 2D drawing representations or sketch views.
Joint Wizard for easily creating joints based on standard woodworking techniques.
Extensive library of easily applied molding and edge treatments.
Visualization of final design using realistic material and environment details.
Optimal layout of bill of materials on existing or recommended stock.
Full API access via a scripting language to the geometry engine and the graphical user interface.
